144606-47-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144606-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,0 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144606-47:
(8*1)+(7*4)+(6*4)+(5*6)+(4*0)+(3*6)+(2*4)+(1*7)=123
123 % 10 = 3
So 144606-47-3 is a valid CAS Registry Number.
